The pion-pion scattering lengths from DIRAC
Description
The scattering lengths of a two pion system are the golden magnitudes to test the QCD predictions in the low energy sector. The DIRAC (PS-212) experiment at CERN will obtain a particular combination of the S-wave isospin 0 and 2 scattering lengths by measuring the lifetime of pionium, the hydrogen-like π+π- atom. This measurement tests the accurate predictions of the Chiral Perturbation Theory. The most recent experimental results are presented
